Computer Science graduate & retail store technology specialist with 5+ years supporting POS/register systems, Cisco networks & connectivity across an 890-store environment. On personal time I ship 0→1 products, internal AI tooling & security tools.
I'm a Computer Science graduate (CSI / CUNY) and a retail store technology specialist with 5+ years at Rainbow Apparel — building, deploying, and personalizing POS systems, Cisco store networks, Inseego connectivity, and peripherals across an 890-store environment, and training 10+ new IT technicians.
Outside the day job I ship 0→1 products, internal AI tooling, and security-focused tools like Asset Vault (a full-stack invoice & inventory platform) and Packet Analyzer — alongside Google Cybersecurity coursework, Security+ prep, and hands-on TryHackMe / HackTheBox labs.
The footprint I keep online every day — registers, Cisco networks, connectivity and peripherals across a nationwide retail fleet. Hover a node to inspect a storeEvery node is a real store (the footprint is real; the telemetry below is a simulation).
I deploy point-of-sale for a living — so here's one, selling the only thing in stock: me. Every item on the register is a real thing I do — store tech by day, full-stack & security builds by night. Add a few, hit checkout, and it prints your quote.
Asset Vault isn't a weekend demo — it's at v2.0.0: invoices, inventory and multi-store analytics behind one type-safe API, still evolving.
AI-assisted diagnostics I built cut troubleshooting time ~40% and overall downtime 30–40% — a store with a dead register is a store losing money.

The problem. Invoicing, stock and multi-store operations usually live in three disconnected tools — totals that don't match, stock counts that drift, and no single view of the business.
What I built. A full-stack platform with end-to-end type safety — React 19 talking tRPC to a NestJS 11 API on PostgreSQL — plus Stripe subscription billing, Puppeteer-rendered PDF invoices and offline-first sync.
The result. v2.0.0 shipped, 50+ schema migrations deep — the type-safe flagship of three sibling invoicing builds (React/Express and Flutter) exploring the same product across stacks.

Three invoicing apps, three stacks — what survives a rebuild is the domain; everything else is negotiable.
